I claim, and desire by Letters Patent to secure, is- A 1. In a device of the character described,

a lens-holding stud or post, la spring, a screw ;.for clampingsaid spring to said stud, said screw having a rigid head provided With a depression in its under side, alocking-plate provided -witha resilient tooth adapted to 'fengage said depression, saidftooth ocated ivo` beneath the headof said screw and projecting laterally therebeyond, and .means for holding said .plateagainst rotary movement.

, 2. In a device othe character described,

a lens-holding stud or post rovided withI a r5 flange thereon, a nose-guar adapted to engagev lsaid flange, a .screw for clamping `said noserguardtosaid stud, said screw having a rigid 1head provided with a depression in its v"'nder sida-,anda locking-plate adapted to zo en age said -ange,' said lockingLplate pro-- vi ed with a resilient tooth ada ted to engage said depression, said tooth ocated beneath the head of said screw and projecting.

-a lens-holding stud or post, a metal plate having a resilient tooth formed thereon, a screw for'- clamping said plate to said stud, said .screw having a rigid head provided with a de- 3o pressionin its under side adapted to receive said tooth, and means for holding said'plate against rotary movement, said resilient tooth being located beneath the head of said screw and projecting laterally therebeyond 3 5 4. Ina device of the' character described,

`a lens-holding stud or post having flanges sanas formed thereon, a metal late adapted to engage said flanges, said p ate having a resili- -ent tooth formed thereon, and a screw for clamping said late to said stud, said screw having a rigid liead provided with a depression in its under side adapted to receive said tooth, said tooth bein located beneath said head and rojecting Iaterally therebeyond.

5. In a evice of the character described, a lens-holding stud or post, a nose-guard, a screw for clamping said nose-guard to said stud, said screw having a rigid head provided with a lurality of depressions in its under side, a ockinglate provided with a resilient tooth adapte to engage one of said depressions, and means for holdmgsaid plate against rotary movement, said tooth being located beneath said head and projecting laterally therebeyond. e

6. In a device ofthe character described, a lens-holding stud or post, a s ring, a screw having a rigld head provide with a plurality of depressions in its under side, a locking-plate provided with a resilient tooth adapted to enga e one of said depressions, and means for olding said plate a ainst rotary movement, said resilient tooth ein located -beneath the head of said screw and projecting laterall therebeyond.
